We Might have a Calf Tonight!

Him: SO we might get another calf tonight.

Me: Oh yeah, how do you know? Is she in labor or something?
Him: .....No

Me: Well, then how do you tell?

Him: Well, her bum starts to swell up and her udder gets tight. I'll probably go check her tonight.

Me: Uh.....like, check her dialation?

Him: No. Just check on her. (I think he rolled his eyes here.) I think she'll probably have it in the morning though.

Me: Poor cow, that's a long labor. Or...... is she a heffer? Should I be saying "Poor heffer" or "Poor cow?"

No answer...
